Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Prior connector housing assemblies suffer from reduced electromagnetic shielding performance due to gaps between partition members and side walls, and the presence of slots for elastic latches further compromises this performance.

Innovation Solution

The connector housing assembly incorporates a partition member with a shielding member that includes elastic contacts extending from both sides, pressing against the side walls to seal gaps and eliminate slots, thereby enhancing electromagnetic shielding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If slots are formed on the partition member to accommodate elastic latches, then the elastic latch can move freely to lock the mating connector, but the electromagnetic shielding performance is reduced

Engineering Contradiction:

Improvelatch movement rangeVSAvoidelectromagnetic shielding performance

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A shielding member is introduced as an intermediary component between the partition member and the housing side walls. This shielding member includes elastic contacts that press against the side walls to seal gaps, while the partition member maintains its slots for latch movement. The shielding member acts as a mediator that restores electromagnetic shielding without restricting latch functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The shielding member utilizes flexible elastic contacts that can deform and press against the housing side walls to seal gaps. These flexible contacts maintain continuous electromagnetic shielding while accommodating the presence of slots in the partition member, as they can adapt to the partition member's structure without requiring solid continuous surfaces.

Inventive Principle:

Principle #30Flexible shells and thin films

2Ease of manufacture

If gaps are formed between the partition member side and the housing side wall, then the partition member can be easily installed and the elastic latch can move, but the electromagnetic shielding performance is reduced

Engineering Contradiction:

Improvepartition member installationVSAvoidelectromagnetic shielding performance

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The shielding member serves as an intermediary that fills and seals the gaps between the partition member and the housing side walls. This allows the partition member to maintain its easy installation characteristics while the shielding member restores the electromagnetic shielding by eliminating the harmful gaps through elastic contact pressure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The elastic contacts of the shielding member change the pressure parameter by pressing against the housing side walls, thereby dynamically sealing the gaps. This parameter change (application of contact pressure) transforms the open gap state into a sealed state, improving electromagnetic shielding without affecting the partition member's installation ease.

Inventive Principle:

Principle #35Parameter changes

3Object-affected harmful factors

If a shielding member with elastic contacts is added to seal gaps and eliminate slots, then the electromagnetic shielding performance is improved, but the device complexity increases

Engineering Contradiction:

Improveelectromagnetic shielding performanceVSAvoidconnector housing assembly structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shielding member is integrated within the partition member structure, combining the shielding function with the existing partition component. This merging approach allows the shielding function to be added without significantly increasing overall device complexity, as the shielding member becomes part of the partition assembly rather than a separate external component.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shielding member with elastic contacts serves multiple functions: it seals the gaps between the partition member and housing side walls, provides electromagnetic shielding, and maintains compatibility with the elastic latch mechanism. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A connector housing assembly comprises a housing defining an accommodation space having a left side wall and a right side wall opposite to each other in a transverse direction of the housing. A partition member is inserted into the accommodation space for dividing the accommodation space into an upper insertion chamber and a lower insertion chamber. A shielding member is installed within the partition member and includes elastic contacts extending from lateral sides of the partition member for pressing on the left and right side walls of the accommodation space.
